How to get rid of flea beetles in the garden. Cruciferous flea: the most effective ways to fight. Biological features of the pest

Insect cruciferous flea, or cabbage (Latin Phyllotreta crusiferae) represents a species of earthen flea beetles of the Kozyavok subfamily of the leaf beetle family. It is found in the Mediterranean region, Europe, the Caucasus, Turkey and Central Asia. Both the adult cabbage flea and its larvae feed on the leaves of plants of the Cruciferous family, or Cabbage - rape, radish, radish, horseradish, daikon, turnip, swede and all types of cabbage.

Cruciferous (cabbage) flea - description

The flea pest is a flying bug with a length of 1.5 to 3 mm with an oval-oblong body and antennae no longer than a third of the body. The flea's hind legs are jumping. The flea beetle species differ in the color of the elytra - they can be black, striped, or with a metallic sheen. Flea larvae feed on thin plant roots. The most harmful are wavy, blue, light-footed, notched and black flea beetles. We will tell you how to deal with flea beetles on cabbage and how to get rid of fleas on other plants.

Flea control in the garden

Fleas on cabbage - how to get rid of

A cruciferous flea appears on cabbage when the air temperature rises to 15 ºC - the beetles hibernate in the surface layer of the soil or under plant debris. Damage caused by flea beetles to cabbage plants may appear as ulcerative gnawing, skeletonization, or interveinal gnawing. If the leaves are severely damaged, they dry out, and this leads to the death of the plant.

A flea on cabbage is dangerous at an early stage of plant development: beetles damage the surface of the stems and leaves, and this causes ulcers that turn into holes - the leaves turn yellow, and damaged seedlings can die in a matter of days, especially if the weather is warm.

You need to destroy fleas immediately, without hesitation. How to treat cabbage from fleas? For early ripening varieties, it is better to use folk remedies, since they are less toxic - weekly spraying with vinegar, ash or tobacco infusion or decoction of tomato tops. And for the treatment of mid-season and late varieties, you can use chemical agents from fleas - Aktar, Aktellik, Decis, Karate or Bankol.

Fleas on radishes or, for example, fleas on radishes or on other root cruciferous crops are no less dangerous than on cabbage, because, by damaging the leaves, they deprive root crops of nutrition. It is necessary to destroy pests as soon as they appear. To completely defeat the cruciferous flea, you need to carry out several treatments.

Fleas on other crops

The cabbage flea does its destructive work not only on cruciferous crops. It also damages roses, levkoi and chrysanthemums. How to deal with a cruciferous flea on flowers? By the same means as in cabbage crops, but in this case, you can use insecticides more safely.

Flea bean treatment is carried out in the evening, after sunset, when insects sit on the leaves of plants.

Flea remedies (preparations)

The most commonly used insecticides to kill cruciferous fleas are:

Aktara- systemic insecticide of contact-intestinal action against many types of pests, including those from sucking and secretive living;
Actellik- non-systemic organophosphate insectoacaricide of contact-intestinal action, used to combat sucking and leaf-gnawing pests;
Karate- combined contact-systemic insecticide against gnawing and sucking insects;
Bankcol- insecticide of contact-intestinal action against gnawing and sucking pests;
Decis- insecticide of contact-intestinal action of a wide spectrum from the group of pyrethroids. Effectively destroys Coleoptera, Lepidoptera and Homoptera.

In addition to the described insecticides, drugs Inta-Vir, Mospilan, Fitoverm and the like can be used against cruciferous fleas.

Fighting the flea with folk remedies

To processing vegetables from cruciferous flea beetles toxic to humans and beneficial insects chemical means should only be used as a last resort. It is better to use in the fight against a pest not so dangerous to health, but no less effective and time-tested means. How to get rid of cabbage flea without using chemicals? We are offering to you folk ways destruction of the cruciferous flea:

freshly planted seedlings should be powdered with wood ash or a mixture of ash and tobacco dust in equal parts. This should be done in dry weather, if the forecast does not predict rain. The treatments are repeated three times with an interval of 4-5 days. It is necessary to cover the leaves of plants with the composition from both the upper and lower sides;
process vegetables with a decoction of tomato tops: 4 kg of fresh tops or 2 kg of dry tops should be crushed and poured over 10 liters of water for 4 hours, then boil over low heat for half an hour, cool, strain, dilute with water 1: 1 and add 40 g of liquid or grated soap. Carry out three sessions of this treatment with an interval of 3-4 days;
scroll a glass of tomato tops and a glass of garlic in a meat grinder, pour this minced meat with 10 liters of warm water, strain, add a tablespoon liquid soap and treat the plants with this composition;
chop half a kilogram of dandelion roots and leaves, dilute with 10 liters of water, strain and add soap;
two glasses of wood ash must be infused in 10 liters of water for 2 days, then carefully drain the water and add a quarter of a bar of grated tar soap to it;
Pour 200 g of tobacco in a bucket hot water, let cool, strain, add a tablespoon of liquid soap or dishwashing detergent;

pour a glass of nine percent vinegar or 2 tablespoons of vinegar essence into a bucket of water, stir and process over the leaves;
boil one kilogram of chopped wormwood for 10-15 minutes over low heat in two liters of water, cool, add 100 g of chopped garlic, strain and bring the amount of broth to 10 liters;
4 kg of potato tops pour 10 liters of water, simmer for 30 minutes, cool, strain, dilute with water in half and process the plants in the evening;
the infusion of chicken manure, prepared in a ratio of 1:20, must be kept for a week in the open air, then strain and spray the leaves of the plants with the infusion. This flea protection agent simultaneously feeds the plants with nitrogen;
dilute 2 tablespoons of flea shampoo from the pet store in a bucket of water and treat the plants with this flea remedy;
make a flag from thin plywood or cardboard, cover it with resin or grease and walk along the rows of cabbage, waving the flag and touching the leaves of the plants. The scattered fleas will jump and stick to the flag. For several such raids, the number of pests in the garden and in the flower garden will be significantly reduced;
Soak the pieces of cloth well in diesel or used car oil, spread them on cardboard sheets between the rows in the cabbage crop at a distance of 4 m.After 2-3 days, turn the pieces over to the other side to collect as many fleas as possible on the cloth.

Cabbage flea - preventive treatment

Everyone knows that it is better to prevent the appearance of pests than to deal with them. Here is a list of preventive measures that will help you keep cruciferous fleas out of your garden:

Cover the newly planted seedlings with a nonwoven fabric. When the seedlings get stronger, and its leaves coarsen and lose their attractiveness to flea beetles, the cover can be removed;
plant the cabbage next to the already risen garlic, coriander or dill, the smell of which scares off the flea. For late cruciferous crops, saving will be mixed landings with marigolds, nasturtium or calendula;
Place bunches of fresh wormwood between the rows of cruciferous crops every day;
add aromatic agents to the water for irrigation - fir or pine oil, corvalol or valerian tincture at the rate of 10-15 drops per bucket of water.

In order to reduce the risk of cabbage flea beetles appearing in the garden to a minimum, the following agrotechnical rules must be observed:

timely and regularly remove weeds in which fleas settle:
in the fall, after harvesting, dig up the soil on the site;
water and feed the plants in a timely manner in order to accelerate their growth and make them unattractive to flea beetles;
plant seedlings in the ground as early as possible, while the flea has not yet woken up, or at the end of June, when it is no longer so scary to the cruciferous.

As soon as tender cabbage shoots appear (or plant seedlings of cabbage), an infinite number of tiny black bugs immediately appear, which pounce on young leaves ... It happens that in a day or two the shoots will be riddled like this (or even completely "cut off" the greens from the shoot ), that you shouldn't even dream of any harvest.

Cruciferous fleas wake up in spring, when the air temperature rises to + 15 ° C, they begin to actively develop, lay eggs and, of course, eat. The beetles scrape off the skin from young leaves and stalks of cabbage and radish, and their larvae eat thin roots ... If there are a lot of flea beetles, tender plants simply die from damage within 2-3 days.

If you don't fight these flea beetles, you can say goodbye to the harvest. We must fight. Moreover, the tools that will help you with this are always at hand. And remember: no need to wait for the fleas to call all their friends for lunch - just planted (sowed) any cruciferous crops, you need to take preventive measures right away!

Folk methods of struggle

So, useful suggestions from experienced summer residents:

Maintaining a humid environment: with The first method is to water the seedlings and seedlings abundantly (the cruciferous flea does not like dampness). Therefore, cabbage, radishes and other crops affected by flea beetles are good for planting in damp (damp) places in the garden.

Dry pollinationleaves: n We run with the help of a gauze bag, simply shaking it (not empty, of course) over the leaves of cabbage, turnip or radish. If you do this in the early morning, when there is dew on the leaves, the repelling dust will stick to the leaves. And fleas do not like such dirty leaves anymore (either the dust sticks to their teeth, or they are afraid of intestinal infections - their problems, but this is in our favor =)

How do we pollinate?

a mixture of wood ash and fluff lime in a 1: 1 ratio;
a mixture of ash and tobacco dust;

a mixture of ash and simple road dust (generally free and available - lying under your feet! =)

Dry pollination of soil between rows

tobacco dust;
with mothballs.

Spraying with infusions and decoctions of herbs

pour boiling water over the ash (in a ratio of 1: 3), insist for two days, add soap (liquid, diluted household soap);
mince 1 cup of garlic and 1 cup of tomato leaves and stepsons. Dilute the mixture in 10 liters of warm water, strain, add 1 tbsp. spoon of liquid soap. Spray with a warm solution;
mince 500 g of dandelion leaves and roots, add water to a bucket, strain, add 1 tbsp. a spoonful of soap;
hot water(10 l) pour 200 g of tobacco, strain, add st. a spoonful of soap;
add 1 glass of 9% table vinegar to 10 liters of water. If there is no vinegar at hand, then 2 tbsp. tablespoons of vinegar essence;
prepare an infusion of green wormwood, you can add garlic gruel there (100 g per 10 l of water). Strain. Watering in small drops;
Pour 4 kg of potato tops with 10 liters of water and boil. Strain the cooled broth and dilute with water by half. Spray in the evenings;
exactly according to the same recipe, you can prepare a decoction from stepchildren of tomatoes.

Shelter for seedlings and seedlings

If you have a lightweight non-woven cover on hand material (spunbond, agrospan or lutrasil), cover young plants with it and feel free to do other things without fear of cruciferous nasty! This material will easily let light, water and air pass through, but flea beetles will have to jump to neighboring areas, where safety measures were not taken care of :))

Catching flea beetles on a sticky flag

Such a flag can be made from thick fabric, thin plywood, and even paper. Attach the cloth to a stick, cover it with a sticky adhesive (for example, grease or resin) and swing it over the plants, preferably slightly touching the leaves. Disturbed fleas jump and ... fall on the sticky layer of the flag. Several passes with a flag along the beds - and the flea population is significantly reduced! These passages are best done during the hottest part of the day.

Sly car service

If you have a car at your side, then flea beetles are just right to shout the guard - they are easy to catch on pieces of cloth, well soaked in used car or diesel oil. It is enough to spread this fabric on iron or cardboard sheets among the beds with cabbage, radishes, turnips and turnips (the distance between the traps is about 4 m). After 2-3 days, the fabric should be turned over to the other side.

Agrotechnical measures

It is important to prevent the mass appearance of cruciferous flea beetles. For this, it is recommended to regularly destroy cruciferous weeds on which beetles "lodge". , digging or - at choice, but it is better that these weeds were as few as possible.

In the fall, you need to dig or plow the soil. The flea, like many other pests, hibernates in the upper layers of the soil, and, once on an open surface, will die from frost over the winter.

Measures that will accelerate the growth and development of seedlings of young plants and seedlings are also very important: these are feeding with organic matter, saltpeter, regular watering and loosening.

Experienced gardeners advise planting cabbage, radishes and other cultivated cruciferous plants next to plants that emit odors that repel flea bees - phytoncides ... These are dill, potatoes, tomatoes, garlic, caraway seeds, coriander, marigolds, nasturtium and calendula.

Well, it is not out of place to adapt to the conditions offered by nature - sowing radish, radish or daikon should be done either early, until the flea wakes up, or later, in late June - mid-July, when the flea is no longer so scary.

Chemical methods

Of course, you can also use chemicals, for example, treat seedlings with solutions of insecticides: karbofos, Aktara, Decis, Arrivo, Sherpa or others (in specialized stores you will be advised quite a lot of effective means). It is best to spray with these preparations in the evening, after sunset. At this time, fleas, as a rule, sit on the leaves. For early ripening plants, it is advisable to use bioinsecticides:

You can find a wide range of biological products for pest control in our catalog, which combines offers from various garden online stores. ...

As soon as the first shoots appear in the spring or plant seedlings, they are immediately occupied by insects hungry for the winter. Cruciferous flea beetles are most active in the garden. The petty dirty trick has nothing to do with true fleas. He got this name because of his jumping abilities. And the cruciferous is called for the love of the cultures of the same name. A large population of cruciferous flea beetles can destroy immature young plants in a matter of days. Therefore, knowledge about what the pest looks like and what available methods can be used to effectively deal with it will not be superfluous.

Biological features of the cruciferous flea

Insects belong to the leaf beetle family. They are widespread in Europe, the Caucasus, Asia, and Western Siberia. All representatives are characterized by an elongated body, the size of which does not exceed 3 mm. The color is predetermined by the species. In the photo of the cruciferous flea, attention is drawn to the long antennae, consisting of 11 segments.

Distinguish from others small pests cruciferous flea beetles are possible by characteristic jumps. "Jumpers" are able to migrate and overcome long distances, due to which they rapidly spread to new territories.

Species diversity

There are several types of cruciferous pests in the world fauna. The most common are the following:

Southern cruciferous, it is also black, is the most dangerous representative of its family in the habitats of fleas. Adults gnaw out the leaves, the larvae damage the young root system. The main difference between flea beetles is the black color of the body with a metallic sheen. The head and elytra are covered with rough punctures. The body length is from 2 to 3 mm.
Light-legged - an inhabitant of the forest belt in the southern regions. Adults gnaw leaves, young individuals harm by mining leaf blades. A distinctive feature of the light-legged cruciferous flea is the resinous strip on the elytra, which gradually tapers in the anterior fragment, and the black, bottle-tinted color of the back and head. Body length from 2.5 to 3.5 mm. The paws are yellow.
Notched is characterized by a black wide suture stripe in the middle part of the elytra or a yellow edging with deep dents. Dimensions do not exceed 2.5 mm. Pruned cruciferous fleas are pests of crops in Yakutia, Primorye, in the Amur region. The adults skeletonize the leaves, and the larvae live in the ground and damage the roots.
The wavy species lives in the northern part of Europe, in the Urals, in Siberia, in the Far East. Adult beetles, like relatives, gnaw foliage. Larvae prefer lateral roots. Feature- a wide black near-seam stripe with bordering yellow, light brown stripes. Pronotum and head are black.

On a note! Insects damage not only agricultural crops, but also decorative and wild ones. Cruciferous fleas inhabit mustard, shepherd's purse, rape, rutabaga, spinach, lettuce, cabbage, radish, young horseradish leaves, turnip, rapeseed, alissum, mattiola.

Lifestyle

Regardless of the species, winter period cruciferous fleas are carried out in adulthood in the surface layers of the earth, under plant debris. With the onset of warmth, they leave their shelters and migrate to weeds, which perform the function of intermediate nutrition. When the first shoots of horseradish, radish appear, cruciferous fleas move to them. Insects are not particularly picky about food, but nevertheless, pests show special love for cabbage seedlings and its young leaves during the formation of the rosette. Farmers also note the appearance of a cruciferous flea on rape in the first, second decade of May.

Adults scrape off the skin from the leaves and absorb the juicy nutrient tissues, leaving behind specific holes. At temperatures from + 15 ° C, fleas begin to actively multiply. Females lay tiny, oblong, yellowish eggs in the soil, where the larvae develop later, for which the roots of the plants serve as food. The size of the eggs is only about 3-0.4 mm in length. The larvae have a thin caramel-colored body on 3 pairs of legs.

The exception is light-legged cruciferous fleas that lay eggs on the leaves of radish, radish. The development of the larvae takes place inside the leaf mass, where they make mines. Oviposition begins in late June and lasts until the end of July. Timing deviations are possible depending on geographic location.

The larvae hatch in 4-14 days. The final stage of development - pupation occurs in the soil in early August. The young beetles that have come to the surface continue to harm the gardens, and in the fall they go into the ground for wintering.

On a note! The increased activity of cruciferous flea beetles takes place in hot weather. A significant increase in the population is recorded during periods of droughts. Rainy weather restrains the number of pests.

Harmfulness of small insects

On cabbage, cruciferous fleas gnaw out indentations that look like sores. It is interesting that they eat only juicy young leaves, and do not touch the old ones. Beetles represent a great danger for seedlings and young seedlings. In immature seedlings, on which insects have settled, the leaves turn yellow, they begin to wither. If the plant has 50 or more individuals, tiny aggressors are able to completely destroy the plantation in 2-3 days.

How to get rid of a pest

How to deal with the cruciferous flea is predetermined by the size of the population, the phase of plant development. It is worth noting that manual picking is an ineffective event, given the miniature dimensions of the bug and its jumping ability.

Agrotechnical measures to combat cruciferous flea beetle:

In the winter period, insects spend in the soil or in the plant litter. Therefore, timely cleaning of all plant residues from the garden will significantly reduce the number of flea beetles and other pests.
For the same purpose, deep plowing of the land is carried out in the autumn. Once on the surface, wintering beetles will die from frost.
Constant harvesting of weeds, especially cruciferous grasses. It is also important to ensure that no weed seeds fall off during disposal. Having lost the food source that the individuals use after wintering, the pests will have no choice but to migrate to other areas in search of a food base.
Feeding plants with fertilizers will help reduce the harmfulness of cruciferous beetles.

The fight against cruciferous flea beetles on cabbage begins at the stage of planting seedlings. It is recommended to land at the maximum early dates or plant by seeds in early spring under the film, in greenhouses. So, by the time the population of beetles appears, the plant will have time to get stronger, the leaves will coarsen and insects will not flatter the seedlings.

Plants such as turnips and turnips are often planted very late. As a result, seedlings appear when the peak of the cruciferous flea beetles has already passed.

Holes with planted seedlings are mulched with tomato stepchildren or tansy. On hot days, the beds are shaded or covered with agrofibre. The edges should be secured and sprinkled with wood ash or hot pepper around the perimeter. To scare off the cruciferous flea, agricultural or ornamental crops are watered with vinegar, chopped garlic cloves, wormwood or dandelion foliage, dill, and caraway seeds.

Catching beetles

Traps are effective safe remedy from a cruciferous flea. The manufacture of devices does not take much time and does not require significant financial costs. How to make a trap yourself:

Construct a kind of flags from available tools. These can be pegs with an attached canvas or plywood, cardboard blanks. Grease one side of the panel with any adhesive (glue, honey, garden pitch, grease). Pick up the received attribute and walk with it along the beds, drawing the lower part over the plants. Fleas are very shy and will actively jump and stick to the sticky fragment. When a fair amount of insects have adhered, remove them and repeat the process. Exercise with a flag is most effective during hot hours and in dry weather.
Make a cone out of cardboard so that it can completely cover the plant. On the inside, also grease with glue and cover the seedlings one by one. A certain part of the flea beetles will stick to the cap.
A less time-consuming option is to lay plywood with glue applied along the beds. When moving along the ground, between plants, insects will stick to simple structures. You can also use a rag moistened with automotive used oil.
A similar effect is given by low, flat containers of water, to which it is necessary to add a little kerosene or vegetable oil so that the prisoners cannot get out of the trap.

Important! Traps with glue, kerosene, diesel oil should be removed during periods of rainy so that harmful components are not absorbed into the soil.

Proven folk recipes

Folk remedies for cruciferous flea beetles have been accumulating for decades. The most effective and well-proven among gardeners are as follows:

Dusting plants with wood ash or tobacco dust, lime, makhorka, ground pepper. It has been noticed that the beetles are unusually "clean" and do not encroach on dirty leaves. The most inventive gardeners sprinkle young seedlings with oven soot. After precipitation, the procedure is repeated.
Planting along the beds of plants that will frighten off cruciferous flea beetles with their aroma. These include garlic, dill, calendula, coriander, marigolds.
Fresh or dried wormwood herb is laid out near the holes.

Plants can be treated with the following decoctions and tinctures for cruciferous fleas:

a bucket of water, 2 glasses of ash and 50 g of crushed tar or green soap;
to spray the leaves, mix a liter of water and a glass of vinegar;
Grind 250 g of freshly skinned dandelions with rhizomes and pour 5 liters of warm water, let it brew, add a bar of soap to improve adhesion;
in a similar way, a mixture of tomato tops (1 cup) and a glass of garlic is prepared;
infusion of chicken droppings (1:20) is infused for several days, after which they are sprayed with foliage.

On a note! It is advisable to spray plants in the morning or evening hours.

Chemicals

If using folk remedies failed to stop the aggressor, insecticides from cruciferous fleas will help. More than 5 beetles on one plant is a serious reason to think about the use of chemicals. It is recommended to initially test the tool on one site. If after a day his condition has not deteriorated, then you can process the rest of the plants.

On a note! In the case when, after the treatment, it suddenly started to rain, the procedure is repeated again.

Preparations from the cruciferous flea beetle for cabbage are presented in specialized stores in a large assortment. Here are just a few of them: Decis, Intavir, Karate, Aktaru, Aktellik, Fagot, Tsapellin, Tabazol, Fitoverm, Aktofit. Before using the funds, you should carefully read the instructions and avoid overdose when diluting the working mixture.

Many summer residents noticed that in addition to typical pests (slugs, stem and strawberry nematodes, ticks, weevils), sometimes a cruciferous flea can literally pounce on strawberries. If nothing is done or if the presence of a pest is not noticed in time, the crop can be seriously damaged. In some cases, it is eaten clean!

One summer resident complains on the forum: “After overwintering on autumn green manures, mustard and rapeseed, the flea ate last year's strawberries and began to taste the recently planted one. Having finished with the strawberries, the pest violently attacked the raspberries ... ". A reasonable question arises: how to stop these insatiable insects and save the harvest at least partially?

Description of the pest

Cruciferous fleas are frequent guests in areas where plants from the Cruciferous family are cultivated or grow independently. The length of these small beetles with a slightly convex elliptical body does not exceed 2-4 mm. The formed beetles can be colored in different colors: metallic green, blue or black. Some have longitudinal yellow stripes on the elytra. Cruciferous fleas not only fly well, but also jump well, for which they got their name. The worm-like larvae are pale yellow in color.

The pest wakes up from winter sleep when the air temperature reaches +15 C and, without any delay or convention, is actively taken to eating young leaves, which quickly turn into a "sieve".

Starving fleas can attack not only cruciferous plants, but also strawberries, strawberries, raspberries and some other crops!

First of all, young leaves are affected, on which many small holes appear in a short time. From the injuries received, plants stop growing and may even die completely.

Control measures

Here are the ways experienced summer residents share:

Dust the affected bushes with crushed wood ash mixed with dry pyrethrum or tobacco dust.
Daily spraying with the following composition: 1.5 tsp. 70% vinegar essence + 2 liters of water.
May be sprinkled with a mixture of dry red and black peppers.
1 tube of the simplest toothpaste (for example, "New Pearl") in a 10 liter bucket of water - water and spray. You can add 50 g of tar soap to the composition (grate and dissolve).
Sprinkle some toothpaste on the strawberries.
Plant dwarf marigolds, dill, garlic, and calendula between the strawberries. The cruciferous flea will then bypass it, and any other infection too.
Insecticides "Aktara", "Pochin", "Provotox", "Aktofit" are extremely effective. Take powder or granules.
Water the attacked strawberries more actively, cruciferous fleas do not like moisture.
If the pest is already on the site, do not plant cruciferous green manures in the fall. They spend the winter on them.

Such things ... And many, like me before, are sure that the cruciferous flea can only appear on cruciferous plants. Of course, she gives preference to them, but she destroys other crops, including strawberries.

The "riddled" leaves of turnip, horseradish or cabbage are often found in the plots. It is all the fault of small gluttonous insects - cruciferous fleas, which in large numbers attack seedlings and tender leaves of seedlings. Often from 50 to 200 pests settle on one young plant.

Colonies of these small insects can destroy the crop in a few days, so in order to preserve it, you must immediately take action. There are several ways to get rid of a cruciferous flea, each of which will be discussed in detail below.

General description and types of insect

This is one of the most dangerous pests agriculture, which can leave the gardener without a crop in a short time. Therefore, it is necessary to know it by sight.

Ash for dusting plant leaves

You can process strawberries and other crops with homemade solutions. The procedure gives a positive result in the fight against bugs. The procedure is carried out only in the evening so that sunburn does not appear on the leaves.

What can be sprayed:

Infusion of chicken manure in a ratio of 1:20. The droppings are poured with water and left for several days, then the leaves are filtered and processed.
Infusion of tomato tops and garlic. One glass of garlic cloves and the same amount of tops are passed through a meat grinder. The porridge-like mass is diluted in 10 liters of warm water, filtered and 1 tablespoon of liquid soap is added.
Infusion of tobacco. 200 g of fresh tobacco leaves are poured into 10 liters of hot water and left to infuse for 3 hours. Then filter and add 1 tablespoon of liquid soap.
You can also scare off bugs with the help of vinegar - 1 glass of 9% vinegar or 2 tablespoons of essence is poured into 10 liters of water.
Decoction of potato tops - 4 kg of fresh tops are poured into 10 liters of water and boiled for 15 minutes. The cooled broth is filtered and diluted with water 1: 1.

Sticky traps

A variety of sticky traps are very effective and safe.

Digging the soil on the site

To prevent the flea from staying on the site, the following measures are applied:

timely destroy weeds, especially those belonging to the cruciferous family, dig up the soil;
if there is already a flea in the beds, then cruciferous siderates are not planted;
be sure to dig up the soil in the fall;
water the soil abundantly, since the insect does not tolerate moisture;
if possible, plants are planted either early, before the flea wakes up, then they have time to get stronger, or at the end of June. In this case, the pest will do less harm;
odorous plants are planted next to the crops.

Despite its small size, the cruciferous flea has an excellent appetite. Preventive measures help reduce the risk of a pest emerging. If insects still settle on plants, action must be taken immediately. A fight started on time is always effective and saves most of the harvest.
